Description

この実施形態においては、粘弾性体と並列にコイルばね12を配置し、粘弾性体とコイルばね12との組合せを除振マウント6として用いている。この実施形態では、粘弾性体を中心に、その周囲にコイルばね12を配置して内外同心状に組合わせた例を示している。 In this embodiment, the coil spring 12 is disposed in parallel with the viscoelastic material 3 is used a combination of viscoelastic material 3 and the coil spring 12 as a vibration-isolating mount 6. In this embodiment, an example is shown in which a coil spring 12 is disposed around the visco-elastic body 3 and combined concentrically with the inside and outside.

本発明において、円柱状の粘弾性体3を空気ばね1の空気室R内に鉛直姿勢で設置している。また、空気室Rには、2段のゴムベローズ2を用いている。ベローズ2には、1〜3段のものが多用されているが、1段のものは水平方向にかたく、また、3段のものは、鉛直方向の伸縮性に優れているが、水平方向には軟らかすぎて座屈が生じやすいという理由から、この実施形態においては、2段のゴムベローズを用いたのであるが、空気室R内には、振マウント6として粘弾性体3と並列にコイルばね12を装填するため、コイルばね12を設置したときには、ベローズ2は、コイルばねに支えられて横ずれが生ぜず、一定の形態に保形されるため、必ずしも2段のゴムベローズに限らず、3段のベローズであっても空気室Rに利用できる。 In the present invention, the cylindrical viscoelastic body 3 is installed in the air chamber R of the air spring 1 in the vertical posture. Further, in the air chamber R, a two-stage rubber bellows 2 is used. Bellows 2 is often used in one to three stages, but one in one is stiff in the horizontal direction, and one in three is excellent in stretchability in the vertical direction, but in the horizontal direction for the reason that easily occurs buckling too soft, in this embodiment, although that used a two-stage rubber bellows, the air chamber R, in parallel with the viscoelastic material 3 as anti-vibration mount 6 When the coil spring 12 is installed in order to load the coil spring 12, the bellows 2 is supported by the coil spring without lateral displacement and is held in a fixed form, so it is not necessarily limited to two stages of rubber bellows. Even three-stage bellows can be used for the air chamber R.

ベローズ2は、上下段のプレート4,5間に設置され、空気室Rは、その内部に形成されたものである。空気ばね1はテーブル7の4本の支持構造であり、空気ばね1の下段プレート5が床上に設置され、上段プレート4上には、直接あるいは脚台(図示略)を介してテーブル7が載せられ、テーブル7上には、図2に示すように機器類16が搭載される。したがって、テーブル7を含めて機器類16の重量が各空気ばねに加わり、コイルばね12はその重量を受けて圧縮され、テーブル7の高さは規定のレベルLに保たれる。 The bellows 2 is disposed between the upper and lower plates 4 and 5 and the air chamber R is formed in the inside thereof. The air spring 1 is a four support structure of the table 7. The lower plate 5 of the air spring 1 is installed on the floor, and the table 7 is mounted on the upper plate 4 directly or through a leg stand (not shown). The equipments 16 are mounted on the table 7 as shown in FIG. Therefore, the weight of the equipment 16 including the table 7 is applied to each air spring 1 and the coil spring 12 receives the weight and is compressed, and the height of the table 7 is maintained at the prescribed level L.

各空気ばね1のそれぞれのベローズ2は、コイルばね12が一定量圧縮された状態で「位置移動する構成物」の位置によって変化する荷重を受けて個々に収縮、膨張する。各脚の空気ばね1のベローズ2の膨張・収縮によって、テーブル7に傾き(揺れ)が生じるが、設定された水平レベルに安定するまでの過渡的な振動・振幅は、空気ばね1のベローズ2内に組み込まれた粘弾性体3によって、効率よく短時間で減衰される。空気ばね1の空気圧によって支持される荷重の大きさ、すなわち、「位置移動する構成物」の荷重(m)は、最大で総重量のせいぜい30%程度である。 The respective bellows 2 of each air spring 1 contract and expand individually under a load which changes with the position of the “position-moving component” in a state where the coil spring 12 is compressed by a fixed amount. The expansion / contraction of the bellows 2 of the air spring 1 of each leg causes the table 7 to tilt, but the transient vibration / amplitude until it stabilizes at the set horizontal level is the bellows 2 of the air spring 1 . By the viscoelastic body 3 incorporated therein , it is efficiently attenuated in a short time. The magnitude of the load supported by the air pressure of the air spring 1, that is, the load (m) of the "position-moving component" is at most about 30% of the total weight.
